ELECTRIcALLY CoNDUCTING LUBRICANT.

1,118,148, Specification of Letters Patent.

No Drawing. Application filed November 21, 1913.

To all whom it may concern Be it known that I, GUSTAV POMHER- HANZ, a sub ect of the Emperor of Austria- Hungary, residing at Belvedere, Prague,

Austria-I-lungary, have invented new and useful Improvements 'in Electrically-Conducting Lubricants, of which the following is a specification.

My present invention relates to a new lubricant having high electric conductivity and especially adapted for use in lubricating relatively moving parts of electrical. machinery and particularly those parts that constitute conductors of electric currents or through which the current is transmitted.

The prime object of the invention is to provide a lubricant or lubricating compound of high electric conductivity; that contains no abrasive materials or properties; that is simple and economical to manufacture and one that can be sold at a nominal price.

I am aware that it has been proposed heretofore to provide a lubricant having electric conductivity, but all previous lubricants of this type of which I am aware, contain solid or insoluble materials or substances that have abrasive properties and these are objectionable because the parts to which the lubricant'is applied wear away more rapidly and because the abrasive materials employed increase the tendency to sparking.

The lubricant forming the subject matter of the present application differs from the prior known lubricants in that it is prepared differently; it is prepared from materials not heretofore employed in a lubricant, and is prepared from materials containing no abrasive properties.

Briefly and generally stated my improved lubricant consists of a lubricating material or substance having a suitable metal salt of an organic acid incorporated therein; and more specifically it consists of an emulsified mixture of a metal salt or salts of an organic acid and a suitable water soluble oil.

In producing my improved lubricant or lubricating compound I first take a salt of a metal as for instance copper, iron, zinc, lead, or other metal salt or a mixture of one or more of these or other salts of metals and according to the well known chemical meth- Serial No. 802,315.

ods transform them into the salts of suitable organic acids, as for instance oleates, stearates, resinates, etc. I then dissolve the salt or salts of the fatty acids so obtained in water-soluble oil, together with water and stir the mixture until well emulsified. This mixture or compound, which is in a. fluid state, may then be used in this form as a lubricant, or it may be given the consistency of ordinary lubricating grease by adding thereto a suitable stiffening substance or material- For this purpose I may employ paraffin, wax, or ordinary commercial soap, either the soft soap or one of the variety of harder soaps suitably dissolved. In the manufacture of my lubricant I may employ any of the known forms of Water soluble oils suitable for the purpose such for instance as Boelegs oil, although I do not wish to be limited-specifically in this respect as other water soluble oils may be employed.

The metal salt or salts of an organic acid employed in the process and compound may consist of stearate of copper, resinate of copper, or ricinoleate of copper'or iron.

The following is one specific example of my improved lubricating compound and method of producing the same: I first dissolve copper hydroxid in oleic acid, and copper oleate is thus obtained. This substance is then dissolved in the proportions of one pound of the copper olea-te to one pound of water-soluble oil, a suflicient quantity of water being added to the mixture to give to it the desired stiffness. The mixture is then stirred until well emulsified. The stiffening agent orv material such as soap, parafiin, or wax, is then added and the whole thoroughly mixed. I

The metal salt of the fatty acid together with the water contained in the compound being good conductors of currents of electricity render the compound highly conductive. The water-soluble oil serves to dissolve the metals salts and at the same time enables the mixture to be emulsified and gives to the mixture its necessary lubricating properties. The wax, paraffin, or soap in the manner and from the materials or substances herein mentioned Will be found to have very high electric conductivity, is non'abrasive in its action, is simple and inexpensive to manufacture, and can be sold at low cost.

What I claim is 1. A lubricant having electric currentconducting properties, consisting of an emulsified mixture comprising a metal salt of a fatty acid and Water-soluble oil.

2. A lubricant having high electric conductivity consisting of a metal salt of an organic acid and Water soluble oil having a stiiiening substance mixed therewith.

3. A lubricant having high electric conductivity, consisting of an emulsified mixture of a metal salt of an organic acid and a Water soluble oil combined with a non fluid stiffening substance.

4. The process herein described of producing a lubricant having electric conductivity Which consists in emulsifying a metal salt of a fatty acid and Water soluble oil.

5. The process herein described of producing a lubricant having electric conductivity Which consists in emulsifying a metal salt of a fatty acid and Water soluble oil with the addition of Water.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
